 * TI Recommends use of the PinMux utility to ensure consistent configuration
 * of pins: http://processors.wiki.ti.com/index.php/TI_PinMux_Tool
 *
 * Zephyr GPIO API however allows runtime configuration by applications.
 *
 * For the TI CC32XX port we leverage this output file
 * from the PinMux tool, and guard sections based on Kconfig variables.
 *
 * The individual (uart/gpio) driver init/configuration functions
 * therefore assume pinmux initialization is done here rather in the drivers
 * at runtime.
